CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant VarietyOffice (CPVO) Plant Breeder's Rights Application No. 2020/0653 filed onMar. 4, 2020 under 35 U.S.C. 119(f), the entire contents of which isincorporated by reference herein.

This application is co-pending with a U.S. Plant Patent Applicationsfiled for plants derived from the same breeding program that areentitled Lonicera Plant Named ‘GRLN02’ (U.S. Plant patent applicationSer. No. 17/135,656) and Lonicera Plant Named ‘GRLN03’ (U.S. Plantpatent application Ser. No. 17/135,656).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Loniceranitida and will be referred to hereafter by its cultivar name, ‘GRLN01’.‘GRLN01’ is a new cultivar of boxleaf honeysuckle, an evergreen shrubgrown for use as an ornamental landscape plant.

The new cultivar was derived from a controlled breeding programconducted by the Inventor at his nursery in Valkenburg, The Netherlands.The overall purpose of the breeding program is to make selections ofLonicera plants with new leaf colors and dense foliage. ‘GRLN01’ arosefrom crosses made in 2014 with Lonicera nitida ‘Red Tips’ (not patented)as the female parent and an unpatented and unnamed proprietary plants ofLonicera nitida from the Inventor's breeding program as the male parent.The seeds were pooled for the crosses and therefore the male parent isunknown. ‘GRLN01’ was selected as a single unique plant in 2015 fromamongst the seedlings derived from the above crosses.

Asexual propagation of the new cultivar was first accomplished by theInventor using softwood stem cuttings in 2015 in Valkenburg, TheNetherlands. Asexual propagation by softwood cuttings has determinedthat the characteristics of the new cultivar are stable and arereproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘GRLN01’ as a new and distinct cultivar of Lonicera.

-   -   1. ‘GRLN01’ exhibits an evergreen, winter hardy habit.    -   2. ‘GRLN01’ exhibits a very dense, well-branched growth habit        that is easy to shape.    -   3. ‘GRLN01’ exhibits foliage that is glossy, fine and green in        color.    -   4. ‘GRLN01’ exhibits clean foliage with no disease problems.

The parent plant, ‘Red Tips’, differs from ‘GRLN01’ in having new shootsthat are burgundy in color and less branching with less dense foliage.‘GRLN01’ can also be compared to the Lonicera nitida cultivar ‘TidyTips’ (not patented), ‘GRLN02’, and ‘GRLN03’. ‘Tidy Tips’ differs from‘GRLN01’ in having a slower growing habit, new shoots that are bronze incolor, winter foliage that is red in color, and leaves that are smallerin size. ‘GRLN02’ differs from ‘GRLN01’ in having foliage that is darkgreen in color with new shoots that are purple in color. ‘GRLN03’differs from ‘GRLN01’ in having new foliage shoots that are orange-brownin color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrates the overall appearanceand distinct characteristics of the new Lonicera. The photographs weretaken of a 7-month-old plant of the new cultivar as grown outdoors in a17-cm container in Wernhout, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘GRLN01’.

The photograph in FIG. 2 is provides a side view of the branches andfoliage of ‘GRLN01’.

The photograph in FIG. 3 is provides a close-up view of the leaves of‘GRLN01’.

The colors in the photographs are as close as possible with the digitalphotography and printing techniques utilized and the color codes in thedetailed botanical description accurately describe the new Lonicera.
